Normally, monthly billing is easy, however the very first billing period is special, as it may span a more than 1 month.

---------------
DATA USAGE ADVISORY
This email has been sent to advise you about your data service usage as of 18-05-2011.
Service "My Example Internet Service"
NATIONAL
You have used 150% of your National data cap.
Used 15GB out of 10GB included in plan.
Excess usage of 5GB charged at $5.00 per GB (exc taxes)
INTERNATIONAL
You have used 84% of your International data cap.
Used 84GB out of 100GB included in plan.
Any future excess usage will be charged at $8.00 per GB (exc taxes)
BILLING PERIOD
Your current billing period ends on YYYY-MM-DD.
{optional} Note:
This billing period is longer/shorter than your regular billing period, this may mean
your data cap allocations appear different to normal to refect the longer/shorter period.
This typically occurs when you first signup to a service, upgrade a service or cancel a service.
